Investigating the killing of a prisoner during a riot inside a state penitentiary, GBI investigator Will Trent is confronted with disturbing information. One of the inmates claims that he is innocent of a brutal attack for which he has always been the prime suspect. The man insists that he was framed by a corrupt law enforcement team led by Jeffrey Tolliver and that the real culprit is still out there. If Will reopens the investigation and implicates the dead police officer with a hero’s reputation of wrongdoing, the opportunistic convict is willing to provide the information GBI needs about the riot murder. Only days ago, another young woman was viciously murdered in a state park in northern Georgia. Is it a fluke, or could there be a serial killer on the loose?
